I agree that a commit cache would solve this (though it can not help the tree traversal). But just dropping the compression (or doing partial decompression when we only care about the beginning part) is way less code and complexity. There's no cache to manage. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
